There will always be someone with a cuter girl, a bigger car, a bigger home, but that does not matter. You measure your own performance by your own potential. That's what makes a successful person.

If you find yourself plagued by a recurrent worry, train yourself to think of something else. Your conscious mind can concentrate on only one thought at a time, and driving the negativity away will free you up to move forward again.

Winners surround themselves with other winners. A winner knows he's a winner. He doesn't need second-raters and yes-men around to feed his ego. He knows he'll win more, and go further, with associates who not only can keep up with him but who also are capable of teaching him something.

Give your subconscious a chance to work by turning your brain off from time to time. Don't focus on work or solving problems constantly.

It isn't the people you fire who make your life miserable, it's the people you don't.

Delegating doesn't mean passing off work you don't enjoy, but letting your employees stretch their skills and judgment.

Don't fall in love with your wit. Your cleverly turned phrase may not, as you hope, show off how much gray matter you have, especially if the phrase is at someone else's expense.
